Abstract
We consider a model of strongly correlated electrons that exhibits superconductivity. It differs from the Hubbard model by nearest-neighbor interactions. We find the ground-state wave function (in one, two, or three dimensions) and show it to be superconducting for attractive and moderately repulsive on-site interaction.Keywords
